## **Features** - Ultrafast recovery - Low reverse recovery current - Low thermal resistance - Higher frequency operation ## **Description** This device is an ultrafast diode based on 600 V Pt doping planar technology. It can be used in hard switching conditions for power factor corrections. Its extremely low reverse recovery current reduces the switching power losses of the MOSFET and thus increases the overall application efficiency. This diode is also intended for applications in power supplies and power conversions systems, and all sorts of power switching. **Table 1: Device summary** |**Symbol**|**Value**| |---|---| |IF(AV)|8 A| |VRRM|600 V| |IRM(typ.)|4.4 A| |VF(typ.)|1.5 V| |Tj(max.)|175 °C| |trr(typ.)|12 ns| - Reduces switching and conduction losses - Insulated TO-220FPAC: - Insulating voltage = 2000 VRMS - Package capacitance = 12 pF February 2017 DocID14277 Rev 2 1/12 This is information on a product in full production. _www.st.com_ **Characteristics** **STTH8S06** ## **1 Characteristics** **Table 2: Absolute ratings (limiting values at 25 °C, unless otherwise specified)** |**Symbol**|**Parameter**|**Parameter**|**Value**|**Unit**| |---|---|---|---|---| |VRRM|Repetitivepeak reverse voltage||600|V| |IF(AV)|Average forward current δ = 0.5 square wave||8|A| |IFSM|Surge non repetitive forward current|tp= 10 ms|60|A| |Tstg|Storage temperature range||-65 to +175|°C| |Tj|Maximum operating junction temperature||175|| **Table 3: Thermal parameters** |**Symbol**|**Parameter**||**Max. value**|**Unit**| |---|---|---|---|---| |Rth(j-c)|Junction to case|TO-220AC,
